Question

i need some help with this geometry

Answer 1

Remember Pythagoras?

Answer 2

a2 + b2 = c2 ??

Answer 3

Yes.

Answer 4

split into right angled triangles
xz=yw
so you have one side 15 and one side 8
you want to work out the hypotonuse
a²+b²=c²

8²+15²=289
square root 289 to get c
c=17

Answer 5

square them and add them and then find the square root yes does it mater witch one is a or b ???

Answer 6

thanks guys for the help :)

Answer 7

ANSWER IS D

Answer 8

c is hypotonuse
a and b are the others it isnt important for a and b

you can re arrange the formula to work out a and b

Answer 9

thanks guys i got this down now thanks to yall :)

Answer 10

use pythagoras theorem
since opposite sides of a rectangle are equal
base=15 inches and altitude=8 inches
Applying pythagoras theorem

\[15^{2}+8^{2} =h^{2} \]
\[\sqrt{289}\]
=17
therefore length of diagonal is 17
